Capulet and all-
These are all good opinions on what happened to radio, but I'd like to add some opinions of my own, for what it's worth(not much, but I'll say 'em anyway!)
It was mentioned on this board somewhere about new talent "cutting their teeth", so to speak, at smaller stations such as Sandusky, or perhaps Mansfield, but those opportunities are long gone, because stations in places like that are pretty much satellite-spewers. Or, if they do have a couple of actual jocks, they spew syndicated garbage during the evening, and have NO overnight person. So, that's pretty much a dead-end...
Also, having the sales department running the programming department was death-knell for creativity within the programming staff. What sales says, goes. Ugh. That's why there's NO overnight jock or anything on except "Coast to Coast AM" worth listening to between midnight and 5am. Sales people don't want to sell overnight spots because they don't make the big commissions, but they fail to realize the "big picture"; IF they sell a LOT of spots to a LOT of clients, they CAN make money. A pile of rocks is a pile of rocks, whether it's made of big rocks or small rocks. I know-stupid analogy, but it does illustrate the point...
I suppose it boils down to this-as long as stations can sell spots, and make some money, they really don't care if anybody listens or not. Sad.
